Reg Traviss insists Amy Winehouse's addictions were "within her control" when she died.
The film director – who dated the late 'Rehab' singer for two years and got engaged to her weeks before she was found dead at her London home in July aged 27 – believes her passing was as a result of the damage she had put her body through during her years of drink and drug abuse, though he insists she didn't drink excessively for her age and was clean of narcotics.
He said in an interview with the Daily Mirror newspaper: "She had been involved with drugs long before we were together. That was way in the past, that was not a bit of her life.
“You couldn’t put her in a room with drugs, it just wasn’t her world any more. She had nothing to do with drugs, had no interest in drugs, all that was in the past.
“The drinking as well, it wasn’t any more than a lot of people her age. I know girls of 27 who work in the City and they drink more than she drank. They binge-drink three or four nights a week.
"But she had all that within her control. What happened was a reaction to the abuse she had put her body through a few years ago.
“These things take a strain and if the body gets strained it takes its toll.
“I believe that’s what it was and I think that the seizures she had been having were a consequence of that.”
Reg is doing his best to move on with his life and has returned to work, but admits he is finding it "tough" at times.
He said: “It’s been foggy, very foggy... very tough. I have started getting back to work and keeping busy, but it’s difficult.
“You start thinking about it, you get down – it brings you down. Amy had turned a corner, that is the tragedy.
“I get good days and bad days. It’s like that really. You are realistic, you understand it and accept it, and then on the flip side everything seems surreal. Even talking about it is strange.”
The inquest into Amy's death is due to reopen tomorrow after it was opened and adjourned on July 25.
An initial postmortem examination proved inconclusive, but her family later said toxicology results had shown there were no illegal drugs found in her system at the time of her death.
